Product Descreiption
The Dongfeng Truck C2402C-025/026 Basin Gear is a precision-engineered crown wheel (ring gear) designed for the rear axle differential systems of Dongfeng’s medium- and heavy-duty commercial vehicles. Tailored for applications requiring robust torque transmission, durability, and quiet operation, this component is integral to ensuring smooth power distribution and traction under demanding conditions. Ideal for trucks, construction machinery, and municipal vehicles, the C2402C-025/026 basin gear combines advanced materials and manufacturing processes to meet the rigorous demands of modern logistics and industrial operations.
Key Specifications
- Application Compatibility:
- Vehicle Models: Fits Dongfeng’s DFL, DFH, Tianlong, and KR series trucks (e.g., 4×2, 6×4, and 8×4 configurations), including cargo trucks, dump trucks, tractors, and specialized vehicles (e.g., fire trucks, garbage trucks).
- Axle Type: Designed for Dongfeng’s 153, 1092, or equivalent single-reduction rear axles, commonly used in medium-duty to heavy-haul applications.
- Gear Ratio:
- Standard Ratio: 4.875:1 (balanced for torque and speed in mixed-use scenarios).
- Optional Ratios:
- C2402C-025: 4.11:1 (higher top speed, ideal for highway freight).
- C2402C-026: 5.143:1 (enhanced low-end torque, suited for off-road or heavy-haul use).
- Material & Construction:
- Gear Material: High-strength alloy steel (e.g., 20CrMnTi or 22CrMoH) with carburizing and precision grinding for superior hardness (HRC 58–62) and wear resistance.
- Tooth Profile: Spiral bevel gear design with optimized contact ratio to reduce noise, vibration, and stress concentration.
- Surface Treatment: Nitriding, shot peening, and anti-corrosion coatings (e.g., zinc-phosphate) for extended service life in harsh environments.
- Dimensions:
- Outer Diameter: ~305–325 mm (12.0–12.8 inches) (varies by ratio).
- Module: 7.5–8.5 (metric sizing).
- Face Width: 42–48 mm (1.65–1.89 inches).
- Weight: ~13–16 kg (28.7–35.3 lbs) (depending on ratio and material).
- Torque Capacity:
- Maximum Input Torque: Up to 4,200 N·m (3,098 lb·ft) (suitable for engines up to 400 hp).
- Load Rating: Designed for GAWR (Gross Axle Weight Rating) of 9,000–14,000 kg (19,842–30,865 lbs).
- Lubrication:
- Recommended Oil: API GL-5 or SAE 85W-90 gear oil.
- Oil Capacity: ~2.5–3.0 liters (0.66–0.79 gallons) for the differential housing.
Technical Features
- High-Efficiency Power Transmission:
- Optimized tooth geometry minimizes friction and energy loss, improving fuel efficiency by up to 2–3% in highway driving.
- Helical gear design reduces noise levels to ≤78 dB under full load, ensuring operator comfort.
- Enhanced Durability:
- Heat-treated gears resist pitting, scoring, and fatigue in high-stress applications (e.g., frequent starts/stops or heavy loads).
- Corrosion-resistant coatings protect against rust in environments with dust, mud, salt, or extreme temperatures.
- OEM Interchangeability:
- Direct replacement for OEM part numbers C2402C-025 and C2402C-026, ensuring compatibility with existing Dongfeng differential assemblies.
- Works seamlessly with aftermarket pinion gears, bearings, and seals.
- Easy Maintenance:
- Modular design allows for quick disassembly and inspection.
- Adjustable backlash settings (0.15–0.30 mm) ensure precise gear alignment and longevity.
